 This function is similar to tvb_bytes_to_str(...) except that 'punct' is inserted
 between the hex representation of each byte.
 
+gchar *tvb_bcd_dig_to_ep_str(tvbuff_t *tvb, const gint offset, const gint len, dgt_set_t *dgt, gboolean skip_first);
+
+Given a tvbuff, an offset into the tvbuff, and a length that starts
+at that offset (which may be -1 for "all the way to the end of the
+tvbuff"), fetch BCD encoded digits from a tvbuff starting from either
+the low or high half byte, formating the digits according to an input digit set,
+if NUll a default digit set of 0-9 returning "?" for overdecadic digits will be used.
+A pointer to the EP allocated string will be returned.
+Note: a tvbuff content of 0xf is considered a 'filler' and will end the conversion.
